Overweight Hispanic girls that listen to rockabilly music and tries to live the lifestyle by squeezing their pudgy sacks of blubber bodies into tight clothing that only hot rockabilly pin-up girls should be wearing.

Derived from the Spanish culinary word of "torta", a thick & fat stuffed sandwich. Because of that, this term should only apply to Hispanic girls that fit the said description.
Miklo: Hey mang, my friend's rockabilly band is playing @ Spikes on Saturday. You wanna go?

Cruz: No, guey. There's too many tortabilly girls (tortabillies: plural form) and I'm not a chubby chaser, ese!

Miklo: Ah, si. Pues, forget it then.

Get the tortabilly mug.
An overweight girl in the rockabilly scene. Usually will attempt to combine extreme plus size modeling with pin up culture, creating an epic fail...

Usually identified by fishnets, hair flowers, and a parasol to keep from cooking in the heat.
OMG look at the size of that pin-up model, shes huge! That must be one of those tortabilly's!!!
